Rare case of subcarinal thymic carcinoma in the middle mediastinum

We report an extremely rare case of a thymic carcinoma occurring in the subcarinal location of the middle mediastinum, masquerading as subcarinal adenopathy. A 6.2 × 5 cm mass was detected on computed tomography scan and found to be hypermetabolic on positron emission tomography scan. Transbronchial biopsy was performed and the mass was found to be suspicious for malignancy. A thoracoscopic resection of the mass was performed and found to be thymic carcinoma. The patient underwent a course of adjuvant radiation. To the best of our knowledge, this is the first reported case of a thymic carcinoma resected from the middle mediastinum.
